About this 3D model

Tank Platform to move around a Web Based WiFi Camera Scaled up version of the original, Now with Gear Reduction, greater ground clearance, spring loaded tension on treads and bearings. All Files.zip contains all the STL files, the SCAD files, The Arduino Tank Code and EasyN Web Code. (Also added Speed Control to Web page and Arduino Code), Need some help getting the web pages to work correctly with IE. Anyone? I have added a basic connection diagram and a few pictures of the internal connections of the EasyN Camera.
